Itchy rash: Rashes are notoriously difficult to solve without seeing them. Hives are like raised patches and can be described as water-filled. Several treatment modalities would help you in that case. Contact allergy may be more likely and an Allergist can help identify triggers and treat that as well.

I have a bright red (and itchy!) rash on the back of both my legs, between my butt and knee. It looks like small bug bite like bumps. Not spreading.?

Allergy consult: The issue is complex and you should consult an allergist. Do realize that even though we can usually control the rash, not uncommonly no cause can be found despite exhaustive studies. In the meanwhile, try taking antihistamine 3 to 4 times a day to see if this may help. The dose needed for itchy skin is much higher than what is needed to control hay fever but even then it may not work. ...Read more
